CAR-'REPLACER.

PECIFICTION forming' part of Letters Patent No. 489,109, dated January 3, 1893. Application filed 'ebrnary 8, 1892. Serial o. 420,798. (No model.)

To all whom it mayconcerng Be it known 7'that I, BURT E. TILDEN, a citi- .zfen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car-Replacers, of which the following is a specification.

My invention relates principally to car replacers for replacing upon the rails, the Wheels of'electrc motors which have become derailed, but it may also be usedto advantage in replacers for-other kinds of rolling stock.

The objects of my invention are to provide a device which will prevent the replacin g frog from slidin`g`when being cngaged by the wheel,

and also'to provide'` a. replaeing frog With which the electric power may be employed in replacing an electric mo'tor.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view, with Wheels .engaging a pair of car replacers. Fig. 2 is a with suitable braces a a a a which serve` tostrengthen the frog, and spurs b b, c c and d d which aid in holding the frog in-'position to the rail when being engaged by a wheel. A metallic strip D is attached to the frog by means of a Wire connection f. as shown in Figs. 2 and 3. The wire connection f; is connected with a ring E in the frog, or `may be attached= to the frog, in any other suitabley manner, and at any desired position in the frog. And if desired any other snitablenpetallic connection may be employed to attach the strip D to the frog.V

The frogA is constructed`with an opening in the side as shown at g in `Fgs. 2 and'f' This renders the frog also suitablelto be used as a hose bridge upon which the car may pass over a fire hose. When being' used for this purpose i-t will of course be necessary to raise the lower end of the frog by any suitable electric power can not be applied to the motor until an electric circuit between the rail and wheel is provided. In order to make this circuit, the frog A is brought in contact with the track at the proper position to the wheel as shown in Fig. 1. Where the track is on 'a paved street the spurs d d of the frog will fit into the narrow space between the track andI paving and hold the frog firmly in contact with the rail as shown'in Fig. 1. For this purpose the spurs d d are made long and thin and are'beveled from both sides so thatl the same may be readily driven into the space between the rail and pavement. When the frog is placed as above stated, the strip D of the frogis placed in contact with the wheel of the motor, and an .electric circuit between the wheel and track beingythus completed, the electric power may be used to propel the Wheel alongthe strip D-upon the frog A, from which it will be thrown upon the rail. The strip D with the connection described, may be placed at such angle to the frogas will be necessary'to`bring it in contact with the wheel, as is shown by the dotted lines in Fig. 2. The strip D also' serves a further purpose in pre- Yenting the frog from slipping when the wheel comes in contact with the same, as the Weight of the Wheel upon the strip D will firfinly hold bot-h strip and frog. 'When the wheelsxbf'the motor are so far pdistant from the rail that the eircnit with the rail cannotbe completed in the manner stated, the frog maybe placed at the proper dist-ance from the rail to engage the wheel, and the circuit may be completed by' joining the frog and rail by any suitable metallic connection, or the strip D may be brought in contact with the rail and the frog may be placed in contact with the Wheel, the

spurs in the frog A ordinarily being sufficient to prevent the frog from sliding when being engaged by the Wheel. In this xnanner, by a series of shifts of the replacing frog, the Wheels may be brought in contact with'the rail.

In operation one frog may -be used or a pair may be empioyed as shown in Fig. 1.

, I do not desire to limit my invention to the use of the stripD with a frog of the kind shown and desc'rib'ed herein, it being obvious that the strip D and connection may be emsubstantially as and for the purposesvdescribed. v

/ 2. The'replacing frog A, having opening g substantiaily. as described and for the pur- -poses specified.

3. In combination with a replacing frog; the

circuit conne'ctng strip'D 'connected With the fro 9; by any suitable means, substantialy as and for the purposes described.

4. In combination with the' replacing frog A, the circuit connecting'strip D'having metallic connection substantially as and for the purposes deseribed.
